Answers
Answer: 5.2 units
Step-by-step explanation:
This is a right-angled triangle which means that the missing length can be solved using the Pythagorean theorem:
c² = a² + b²
Where c is the hypotenuse
a and b are the other sides.
c = 6
a = 3
b = ?
6² = 3² + b²
36 = 9 + b²
b² = 27
b = √27

C=-a/b what does a equal
Answers
Answer:
a = -bc
Step-by-step explanation:
We are given the equation:
c = -a/b
Because multiplication and division are inverse operations, if we move b over to the other side, since it was dividing on the right side, it would be multiplied on the other side (I don't know how to explain that well)
so you can make it look like this:
b*c = -a
Or:
-a = b*c
Then, do isolate a, we will have to divide by -1 on both sides
a = -b*c
To check this, we can plug in numbers
-8 = -16/2
-16 = -8*2
16 = 8 * 2

Answer:
y=3
Step-by-step explanation:
you just need to do 2 divided by 6
Answer: y = -3/2x + 3
Step-by-step explanation:
3x + 2y = 6 First Isolate y by subtracting 3x from both sides
-3x -3x
2y = -3x + 6 Now divide both sides by 2
y = -3/2x + 3

Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.
Step-by-step explanation:
Let [tex]x[/tex] denote the number of rafts seating 3 people and [tex]y[/tex] the number of rafts seating 5 people. The total number of rafts is 13, so [tex]x+y=13[/tex]. We can also assume that every raft is filled to the brim (it isn't stated explicitly though, but it's probably the intention of the question maker), so [tex]3x+5y=53[/tex].
It's always a good idea to put these equations under each other:
[tex]\left \{ {{x+y = 13} \atop {3x+5y=53}} \right.[/tex]
We can subtract the first equation three times from the second one to obtain [tex](3x+5y)-3(x+y) = 53 - 3(13)\\3x-3x + 5y - 3y = 53 - 39\\2y = 14\\y=\frac{14}{2} = 7[/tex]
Now, substitute this found value for [tex]y[/tex] into [tex]x+y = 13[/tex] and we see that [tex]x=6[/tex]. We are now done: Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.

1. What is the value of n in -57 - n = -144?
A-201
B-87
C 87
D 201
Answers
Answer:
C=87
Step-by-step explanation:
To isolate the variable, you need to take away -57 by adding it to -144.
Then, you'd see:
-n=-87
Next, you divide both sides by -1 to get 87

Answer:
[tex]y = \frac{4}{5} x -9.8[/tex]
Step-by-step explanation:
I hope this is what you were looking for.
Answer:
y=4/5x-9.8
Step-by-step explanation:
For this you would need to use point-slope form which is: y-y1=m(x-x1)
All you have to do is put in -5 for y1, 6 for x1, and 4/5 for m.
So, the equation should then be y+5=4/5(x-6)
Then, start by solving the right side of the equation by distributing 4/5 into (x-6)
This will then leave you with the equation, y+5=4/5x-24/5
Next, you have to subtract both sides by 5.
Once done, your final answer should be y=4/5x-9.8

Three different accounts are described below. Order the accounts according to their values after 10 years, from greatest to least.
You deposit $950 in an account that earns 9% annual interest compounded daily.
= You deposit $1000 in an account that earns 8% annual interest compounded daily.
= You deposit $1000 in an account that earns 9% annual interest compounded semiannually.
= You deposit $1000 in an account that earns 10% simple interest.
Answers
Answer:
`1. You deposit $950 in an account that earns 9% annual interest compounded daily.
2.You deposit $1000 in an account that earns 8% annual interest compounded daily.
3. You deposit $1000 in an account that earns 9% annual interest compounded semiannually.
Step-by-step explanation:
Trick question, number 3 says semiannually so it is only twice a year, so it is the least. In math papa or any algebra calculator, put in the two equations and compare which is greater, in this case, y = 950(1.09)^10 is greater than y=1000(1.08)^10
Accounts according to their values after 10 years, from greatest to least. are Account 3, Account 1, Account 2 and Account 4.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
The formula for daily compounding is:
[tex]A = P(1 + r/n)^{nt}[/tex]
where A is the future value,
P is the principal amount,
r is the annual interest rate,
n is the number of times the interest is compounded per year, and t is the time in years.
When we deposit $950 in an account that earns 9% annual interest compounded daily.
A = 950(1 + 0.09/365)³⁶⁵⁰
= $2,436.24
Deposit $1000 in an account that earns 8% annual interest compounded daily.
A = 1000(1 + 0.08/365)³⁶⁵⁰
= $2,223.97
Deposit $1000 in an account that earns 9% annual interest compounded semiannually.
A = 1000(1 + 0.09/2)²⁰
= $2,471.52
Deposit $1000 in an account that earns 10% simple interest.
The formula for simple interest is:
A = P(1 + rt)
where A is the future value, P is the principal amount, r is the annual interest rate, and t is the time in years.
Using this formula, we get:
A = 1000(1 + 0.10(10))
= $2,000
Now we can order the accounts from greatest to least based on their future values after 10 years:
Account 3: $2,471.52
Account 1: $2,436.24
Account 2: $2,223.97
Account 4: $2,000
Hence, accounts according to their values after 10 years, from greatest to least. are Account 3, Account 1, Account 2 and Account 4.
